Millions of creators around the world use CC licenses to give others permission to use their work in ways that they wouldn’t otherwise be allowed to. Those millions of users are the proof that Creative Commons works.
But measuring the size of the commons has always been a challenge. There’s no sign-up to use a CC license, and no central repository or catalog of CC-licensed works. So it’s impossible to say precisely how many licensed works there are, how many people are using Creative Commons licenses, where those people are located, or how they’re using them.
With this report, we’re taking a big step toward better measuring the size of the commons. We’re also sharing all of the data and methodologies that we used to find these numbers, and making a commitment to hone and update these findings in the months and years to come. We’re also telling the stories of events from 2014 that have impacted the size, usability, and relevance of the commons.
